These constants define different non-uniform rational Bi-spline flags.
Values:
IG_VECT_NURBS_UNIFORM | The spline is uniform. |
IG_VECT_NURBS_RATIONAL | The spline is rational. |
IG_VECT_NURBS_MCLOSED | The spline is closed in M-direction. |
IG_VECT_NURBS_NCLOSED | The spline is closed in N-direction. |
IG_VECT_NURBS_MINTERPOLATE | The curve must be interpolated in M-direction. |
IG_VECT_NURBS_NINTERPOLATE | The curve must be interpolated in N-direction. |
IG_VECT_NURBS_MFIT | Not currently used. |
IG_VECT_NURBS_NFIT | Not currently used. |
